Key takeaways
- The closer body is non-handed, while the optional metal cover and the two hold open extra duty arms are listed as handed.
- Three labeled valves control the hydraulics: backcheck cushions the opening swing, main speed controls the closing swing to within a few degrees of latch, and latch speed those last few degrees.
- Delay action, an option, delays the first part of the closing swing to give more time to pass through the door.
- Plated finishes and custom powder coat finishes require the optional metal cover.
Identify
Which 4040XP arm and mounting do I have?
This page covers the LCN 4040XP Series closer with its double lever arms, a two-piece arm with a joint in the middle.
The arm's far end fastens to a shoe, a small bracket on the frame or door. On a Cush-n-Stop arm the shoe is a soffit shoe, fixed under the frame head, with a built-in door stop. The 4040XP ships with the regular arm, a double lever, non hold open arm; every other arm in the table below is optional.
The product configuration chart marks four options as not available on the 4040XP: a fusible link arm, a standard (single lever) arm, a double egress arm and the advanced variable backcheck cylinder.
Hold open arms and their angles are on the page about LCN hold-open closers. For whether any closer needs adjustment, repair or replacement, see the general guide to commercial door closer repair, adjustment or replacement.

Sizing
What size is the closer, and which door width does each size suit?
In LCN's terms, size refers to the minimum spring power, and hence the closing force, generated by the closer, and the width of the door is the main consideration in determining the correct size.
The 4040XP has a non-sized cylinder: the closer body, which holds the spring and hydraulic fluid, has spring power adjustable over a range of sizes. LCN lists its spring size as adjustable from 1 to 6, with the LCN Green Dial, a visual reference of the spring power setting. Cylinders are shipped set to size 3, and LCN's catalog says closing power "may be adjusted 50%."
The table sets the catalog's width marks for each size beside the different widths in the installation instructions' chart. A footnote under the catalog's table of sizes reads "Adjustable Size 1 thru 5." LCN's product page puts the reach as interior doors to 5'0" and exterior doors to 4'0".
| Size | Exterior (and vestibule) door, catalog | Interior door, catalog | Exterior door, installation instructions | Interior door, installation instructions |
|---|---|---|---|---|
| Size 2 | Not listed | Between the 24 in. (610 mm) and 30 in. (762 mm) marks | No door width given | 34 in. |
| Size 3 | Between the 24 in. (610 mm) and 30 in. (762 mm) marks | Between the 30 in. (762 mm) and 36 in. (914 mm) marks | 30 in. | 38 in. |
| Size 4 | Between the 30 in. (762 mm) and 36 in. (914 mm) marks | Between the 36 in. (914 mm) and 48 in. (1219 mm) marks | 36 in. | 48 in. |
| Size 5 | Between the 36 in. (914 mm) and 42 in. (1067 mm) marks | Between the 48 in. (1219 mm) and 54 in. (1372 mm) marks | 42 in. | 54 in. |
| Size 6 | Between the 42 in. (1067 mm) and 48 in. (1219 mm) marks | Between the 54 in. (1372 mm) and 60 in. (1524 mm) marks | 48 in. | 60 in. |

Mounting
Will it fit my door and frame?
Below, the stop is the strip of frame the door closes against, the top rail is the top part of the door, and the head frame is the top piece of the frame. The 4000 Series closers can be used with a hinge or pivot mounted door and are not designed for exterior mounting or exposure to elements.
Parallel arm mounting requires the parallel arm (PA) shoe, 4040XP-62PA, and adds the prefix P to the closer description: the P4040XP, which includes a 4040XP-201 fifth hole spacer to support the shoe.
LCN's documents give two figures for when a parallel arm mount needs plate 4040XP-18PA. The catalog's mounting table says a top rail less than 5-3/8 in. (137 mm), measured from the stop; its accessories page and the cut sheet say less than 5-1/2 in. (140 mm). The catalog's how-to-order list prints this plate as "Plate, 4030-18PA."
For the installer, the EDA arm can be templated (laid out from LCN's template) for points at 110° or 180°, and CUSH arms for an opening point at 85°, 90°, 100° or 110°. Spring Cush stop points are approximately 5° more than the templated stop point. Closers ordered with either arm include the same spacer. A flush or rabbeted head frame requires the CUSH flush panel adapter, and a CUSH arm requires shoe support 4040XP-30 where the reveal is less than 3-1/16 in. (78 mm).
| Item | Hinge (pull) side | Top jamb (push) side | Parallel arm (push) side |
|---|---|---|---|
| Butt hinges | Should not exceed 5 in. (127 mm) in width | Should not exceed 5 in. (127 mm) in width | Should not exceed 5 in. (127 mm) in width |

Valves
What do the valves and delay action on a 4040XP control?
The closer body has back check, main and latch regulation valves, labeled to match a diagram of door swing zones on the body. A positive stop on all regulation valves prevents the screw from being backed out and causing accidental damage, and color indicators show how far a screw is backed out: "the more visible the component, the faster the speed."
The installation instructions note: "A 'Normal' closing time from 90° open position is 5 to 7 seconds, evenly divided between main speed and latch speed." They also print "NO MAINTENANCE REQUIRED" and a caution that opening of regulation valves too far may result in leakage of the closer, personal injury or property damage.
If a 4040XP slams, stalls or will not latch, that is a service call, not a valve for building staff or residents to turn.
Delay action, a special hydraulic circuit that provides additional time to pass through the door, uses the optional delay action cylinder (CYLDEL). The 4000 Series catalog's mounting tables, repeated in the table below, give where the delay ends for each mounting, and in every case delay time is adjustable up to approximately 1 minute.
The general information catalog gives a different end point: a special regulating screw controls the closing speed from maximum opening through approximately 75°, after which the normal main speed resumes control. It adds that delayed action is not available with single lever arm (track) closers.
| Valve or delay action | What LCN lists |
|---|---|
| Backcheck | A hydraulic circuit designed to cushion the door's opening swing. Standard on all LCN closers. |
| Main speed | The closing swing of the door to within a few degrees of latch. |
| Latch speed | The last few degrees of the door's closing swing. |
| Backcheck selector valve | Used to provide proper backcheck location for 4040XP and 4050A parallel arm mounting. On the backside of the closer cylinder, directly opposite the backcheck regulating valve. |
| Delay speed | Labeled in the installation instructions as a fourth valve on the optional 4041 delay cylinder, beside backcheck, main speed and latch speed. |
| Delay action, hinge side, top jamb and parallel arm | Delays closing from 120° to 70°; delay time adjustable up to approximately 1 minute |
| Delay action, EDA and CUSH, 180° template | Delays closing from maximum opening to 115° |
| Delay action, EDA and CUSH, 110° template | Delays closing from maximum opening to 95° |
| Delay action, EDA and CUSH, 100° template | Delays closing from maximum opening to 85° |
| Delay action, EDA and CUSH, 90° template | Delays closing from maximum opening to 75° |

Options
Which cylinder, cover, finish and screws does it come with?
Unless options are selected, the closer ships with a standard cylinder, standard cover, regular arm and self reaming and tapping screws (screws that cut their own thread).
An optional special rust inhibitor (SRI) pre-treatment, "for installations where a higher level of corrosive resistance is required," is for powder coat (baked-on paint) finishes only.
LCN recommends wood screws, available in optional WMS screw packs, for wood door applications.

Fire doors and accessibility
What does LCN list for fire doors and opening force?
The catalog gives the 4040XP's certifications as "Grade 1 - ANSI A156.4, UL 10C, ADA." Those are the ANSI/BHMA standard for door closers, UL's positive pressure fire test for door assemblies, and the Americans with Disabilities Act.
For the 4000 Series, the catalog's listings read: "UL listed for self-closing doors without hold open under 'swinging door closers' (GVEV) file R1943. Tested and certified under ANSI Standard A156.4 Grade One." On positive pressure: "LCN closers have been certified for three hours by UL to be in compliance with UL 10C. Contact LCN for specific details on door closer fire ratings."
LCN's two documents differ on the Canadian listing (cUL). The catalog says to consult the factory for other listings such as cUL, California State Fire Marshal, and Bureau of Standards and Appeals. The cut sheet says the closer is "cUL listed and UL listed for self-closing doors without hold-open."
Opening force is how hard someone has to push or pull to open the door. The cut sheet says the 4040XP is "Available with less than 5.0 lbs. opening force on 36" door."
The catalog's reduced opening force table lists the 4040XP for door widths of 36, 42 and 48 in. at maximum opening forces of 8.5 lbs. and 5.0 lbs. Beside that table is a caution: "Any manual door closer, including those certified by BHMA to conform to ANSI Standard A156.4, that is selected, installed and adjusted based on ADA or other reduced opening force requirements may not provide sufficient power to reliably close and latch a door."
The caution refers readers to LCN's Automatic Operators catalog for systems that meet reduced opening force requirements. See LCN low-energy door operators.

Related LCN closers
How the 4040XPT, 4011, 4111 and 4040SE differ from the 4040XP
On a track closer, such as the 4040XPT, a single arm with a roller slides in a track, in place of the double lever arm.
In LCN's general information catalog, SE is electrically controlled hold open using a special track and single lever arm; the 4040SE is on the LCN hold-open closers page.
| Closer | What it is | Handing | Spring size | Mounting |
|---|---|---|---|---|
| 4040XP | Double lever arm closer | Non-handed | Adjustable 1-6; a footnote under the catalog's table of sizes reads "Adjustable Size 1 thru 5" | Hinge (pull side), top jamb (push side), parallel arm (push side) |
| 4040XPT | Track version: standard arm and track with roller | Non-handed | Adjustable 1-4 | Pull side on door, pull side top jamb, push side on door |
| 4011 | 4010 Series cylinder | Handed | Adjustable from size 1 to 5; sized 4010 Series cylinders are available in size 6 | Hinge (pull side) |
| 4111 | 4110 Series cylinder, with an extra-duty arm; LCN offers an advanced variable back check cylinder (CYLAVB) for the series | Handed | Adjustable from size 1 to 5; the sized 4116 cylinder is size 6 | Parallel arm (push side) |
